hi everyone, i don't know if everyone on cosmo-torun is on cosmo-pl. Anyway, i sent the following to cosmo-pl. pozdr boud

Witam cosmo-pl,

The 3-year WMAP data is now available: http://lambda.gsfc.nasa.gov/product/map/dr2/ilc_map_get.cfm

As expected from the Poincare Dodecahedral Space analyses, e.g. http://arxiv.org/abs/astro-ph/0310253 Luminet et al. http://arxiv.org/abs/astro-ph/0402608 Toruń http://arxiv.org/abs/astro-ph/0412569 Aurich Lustig Steiner http://arxiv.org/abs/astro-ph/0503014 Gundermann http://arxiv.org/abs/astro-ph/0504656 Aurich Lustig Steiner

the estimates of Omega_total remain in the range 1.010-1.020. :))))

Spergel et al find:

http://lambda.gsfc.nasa.gov/product/map/dr2/pub_papers/threeyear/parameters/...

Omega_tot = 1.015 (+0.020,-0.016) WMAP-3yr + SNLS (supernova legacy survey) 1.010 (+0.016,-0.009) WMAP-3yr + HST key project on H_0

No matter how hard people try to combine different data sets, it seems that nobody can get Omega_tot much closer to 1.000 (except by assumption).

In the conclusion, section 9, page 61 of Spergel et al., you'll see that after people like me have repeated ad infinitum in many, many seminars etc that WMAP does not imply a flat Universe, it only implies a "nearly flat Universe", finally, Spergel et al. have started using this expression:

"The WMAP data are consistent with nearly flat universe".

:)

Anyway, hopefully in the next week, i and the other people who have volunteered ;) to help organise a small, "polish cosmology" workshop/meeting in Toruń, probably in May, will send out a "pre-registration" announcement...
